AI Bug Fixer — Find and Fix Code Errors in Seconds
Paste broken code or an error message and get the fix, plus an explanation of what went wrong and why.
What is AI Bug Fixer?
Cobain AI's AI Bug Fixer helps you debug faster. Paste the code that's failing — or just the error message and stack trace — and the AI pinpoints the problem, returns a corrected version, and explains what caused it. It's a fast second pair of eyes for syntax errors, logic bugs, runtime exceptions, and tricky edge cases across many languages.
Key features
Find and fix the bug
Paste broken code and the AI returns a corrected version that addresses the error.
Plain-English explanations
Understand the root cause, not just the fix, so you avoid the same mistake again.
Works from error messages
Paste a stack trace or error log and the AI traces it back to the likely cause.
Many languages supported
JavaScript, Python, TypeScript, Java, C#, PHP, Go, SQL, and more.
Catches logic and edge cases
Goes beyond syntax to spot logic bugs, off-by-one errors, and missed conditions.
Suggests improvements
Often points out cleaner or safer ways to write the fixed code.

Frequently asked questions
Is the AI bug fixer free?
Yes. You can start fixing bugs for free with a Cobain AI account, with paid options for heavier usage.
Which languages does it support?
Popular languages including JavaScript, TypeScript, Python, Java, C#, PHP, Go, and SQL. Mention the language for the best result.
Can I just paste an error message?
Yes. Pasting the error or stack trace alongside the relevant code gives the AI the most context to find the cause.
Does it explain what was wrong?
Yes. The AI explains the root cause in plain English so you understand and avoid the bug in the future.
Will the fixed code always work?
It resolves most common bugs, but you should always review and test the fix in your own environment before shipping.
Can it find logic bugs, not just syntax errors?
Yes. It can catch logic errors, off-by-one mistakes, and missed conditions, not only syntax problems.
